Answer:
The surface area is the area that describes the material that will be used to cover a geometric solid. When we determine the surface areas of a geometric solid we take the sum of the area for each geometric form within the solid. The volume is a measure of how much a figure can hold and is measured in cubic units.
Step-by-step explanation:
In a pond there are 56 fish.
12 of the fish in the pond are red that means that 44 of the fish are not red.
We can use the fraction to represent the 12 red fish out of all the fish together.
can be reduced by dividing both the numerator and denominator by the greatest common factor of 12 and 56. reduced is .
3 ÷ 14 = 0.21428571428571
0.21428571428571 × 100 = 21.428571428571%
Therefore, 21.428571428571% of the fish are red.
